Specification of Letters Patent.

Patented Apr. 2 1-, 191?.

Application filed December 10, 1915. Serial No. 66,187.

T 0 all whom it may concern Be it known that 1, HARRY Srnnnnsnnc, a citizen of the United States, and a resident of the city of Newfolden, county of Marshall, and titate of Minnesota, have invented certain new and useful Improvements in Selfserving Dining-Tables, of which the following is a specification.

My invention relates to improvements in self-serving dining tables, and more particularly to that type of self-serving tables which involves the use of a rotary center or disk. The object of my invention is to produce a device of this character which shall be simple and durable in construction, attractive in appearance, efficient in operation and inexpensive of manufacture. Other objects will appear from the embodiment of these specifications, which show a preferred form of my invention, it being understood that I do not wish to limit this invention to this preferred form, but claim such latitude as shall come within the scope of the spirit and claims of these specifications.

The invention will be best understood by reference to the accompanying drawings, which form a portion of these specifications, and in which:

Figure 1 is a plan view of the table top from which the center disk or portion has been removed.

Fig. 2 is an elevation of the table taken partly in section on the broken line 2-2 of F 1.

Fig. 3 is a plan view of the under side of the rotary center or disk.

Fig. 4 is a side elevation of the rotary center taken partly in section on the broken line H of Fig. 3.

With more particular reference to the drawings, the numeral 1 indicates the pedestal supporting the table top, and which itself is supported by the customary feet and casters; 2 is the outer or external annular portion of the table top which is supported on the disk 3, which in turn is supported on and attached to the pedestal 1. The top 2 is reinforced by an annular ring 4, the further purpose of which ring will presently appear; 5 indicates the recess in the annular top 2 to provide for the reception of the rotary center or disk 6, which center rides on, and is supported by, suitable casters or ball bearings 7 which roll upon a suitable annular plate or ring 8, resting on the disk 8 inside the opening The center 6 is located within the opening 5 by the stud or pin 9 co-actin with the center depres- 1 2' 1 sion or socket 10. The under side of this rotary center is also provided with a plurality of pins or lugs 11 invannular forma tion. Located beneath the annular top 2 is a plurality of bars 12, provided with catches or hooks 13 for engagement with the lugs 11, the inner ends of the bars 12 being refiexly curved, as at 1%, for purposes to be hereafter described, the outer extremities of these bars being); formed into convenient loops or finger holes 15. The outer ends of bars 12 are retained within, and supported by, recesses 16 in the annular reinforcing ring 1, the inner end being downwardly flexured to pass beneath ring 8, suitable openings 17 being provided for this purpose in disk 3, which openings may be provided with suitable resilient stops or bumpers 19 to limit the travel of bars 12 in an inwardly direction, this travel being induced by the extension springs 18. Lateral motion of the inner extremities of bars 12 is provided for and retained within definite limitation by the staples 20, these bars being compressed against the inner extremity of these staples, or of the openings 17 by the leaf-spring 21.

From the foregoing it will be evidentthat when the center disk is properly positioned within the annular opening of the table top, the catches 13 will co-act with the lugs 11, and when bars 12 are moved manually out wardly against the action of springs 18 by an operator drawing on finger holes 15, it will cause a segmental rotation of this cen ter portion, and on release of the bar 12 by the operator the spring 18 will return said bar to its more central position, the reflexly curved portion 1 1 co-acting with the lug 11 which has become advanced to its new position to force bar 12 and catch 13 outwardly against the action of spring 21 to allow catch 13 to again come into operative position for lug 11. It is also evident that when but one of the bars 12 has been manually operated. the lugs 11 in their annular advancement will co-aot with the portions 14 of the other bars to force them simultaneously outward against the pressure of their respective springs 21, so that each and every catch 13 is at all times in operative position with its respective lug 11, so that any person seated around the table may at any time cause the annular segmental rotation of the center portion by manually operating any of the bars 12.

Having thus described the preferred form of my invention, What is claimed asneW, and What I desire to protect by Letters Patent, 1s:

1. In a device of the character described, a stationary annular top With arevoluble central portion supported on suitable bear- I ings, and provided with a plurality of operating lugs on its under side, a plurality of longitudinally and horizontally movable bars, each provided at its inward extremity With a suitable hook or catch to co-act With said lugs, and having external cam faces for horizontally operating said bars; and

springs for returning said bars to their retracted position after operation.

2. In a device of the character described, a stationary annular top, provided With a revoluble center portion, supported on suitable bearings, and provided With a plurality of operating lugs, and in combination there with a plurality of operating bars to coact with saidlugs, and means for automatically returning these bars to their normal position after operation.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
